Default Converting Kilograms to liters

I need to convert 390.2 Kg to liters. The specific gravity is 1.2104. From everything I read, you multiply. Is this correct? If multiplying, I come out with 472.298 liters. If dividing I come out with 322.372 liters. Is that anything with a specific gravity of less than 1 is multiplied, and anything with a specific gravity greater than 1 is divided?

Thanks,


DC

Specific gravity is the density of the substance as compared to water. Water has a density of 1 kilogram/liter. So a specific gravity of 1.2104 means it has a density of 1.2104 kilogram/liter

Using algebra we know whether to multiply or divide to make one of the units cancel out.

kilograms / (kilogram/liter) = liter
liters * (kilogram/liter) = kilogram

So in your case, you divide:

390.2 kilograms / 1.2104 kilograms/liter = 322.3728 liters

Whether you multiply or divide does not depend on if the specific gravity is above or below zero, it only depends on which direction you are going, from kilogram to liter or from liter to kilogram.

If your tank holds water, then 30,000kg = 30,000L. If the material is something other than water, you could post the substance, and someone may be able to find the density.

Think of it this way

If the specific gravity is >1 : the fluid weighs more and has fewer liters

eg. specific gravity 1.5 would mean 3000 kg = 1500 liters

specific gravity 0.5 would mean 3000 kg = 4500 liters

You would either multiply the liter side or divide the kg side.


kg side liter side
3000/1.5 = 1500
or
3000 = 1500 * 1.5

or
3000 = 1500 * 1.5
It might have changed, but when I went to school, 1500 x 2 = 3000

What is the water equivalent of CNG

i.e. 1 liter of water = How many KG of CNG (Compressed Natural Gas)

Density can vary between refinies and between batches. But .837 kg/L seems typical of #2 conventional diesel (US Dept. of Energy data). So that would be about 188 kg.

If you have a density figure specific to your lot of diesel fuel, use it instead.

Hi,

Suppose the water is flavoured, is it then 1 kg = 1 liter.


Thanks
